I have a MacBook Air, 2009, with a recently replaced Apple battery in December 2012. Recently, when power cord comes off, the computer shuts down. Also, it usually will not restart unless power cord is attached. How to download sims in sims 4.
Any help with this would be appreciated.

Your battery gets not charged properly. This can mean different things. Start inspecting all the different components involved.
Try resetting SMC first and only after a SMC reset did not solve your problem you should think about replacing your battery.
The other two answers already explain everything you need to know about each of those steps very well.
But you should also check all the components and connections your current passes through: power adapter, MagSafe connection pins, MagSafe connection at your laptop. If, for example your MagSafe connection is not stable, your SMC could get into trouble: are all the pins ok or is one stuck? This happened to a MacBook Pro we have and as a result we had to buy new Batteries continuously until we found out, that the pins apparently did not have a stable connection. A screwed up SMC could be at the cause of all your troubles and in that case the question is: why did it screw up?
In our case the MBP stopped holding charge and did not charge. A SMC reset + MagSafe cleaning helped in our case, but we will probably have to buy a new power adapter.
When your MagSafe connection works you should get proper feedback from the LED.
From experience I can say that a screwed up SMC can put excessive stress on a battery and destroy it in a very short time.
Good luck!

The battery is dead.
The computer (in this case your MacBook Air) turns off because there is no more/not enough charge in the battery. If it's necessary to have the power adapter plugged in when trying to turn it on, it's a sure sign that the battery is discharged.
There are a number of utilities that you can get (paid and free) that will look at your battery status:
These are all good, but in my opinion, I would much rather use built in tools to get this info.
Excel button to change data on dashbord. If our old school excel templates does not like we are back to square one. If you are excel power user and bored with old templates then you should have a look at brand new design and layout.
Using Terminal, just issue the command:
That will give you all the power settings related to your Mac. The output can be rather lengthy; the info you need will be at the top. You can limit it to just the battery info by tweaking the command as follows:
Results:
Here we can see that the battery is in need of service. (Coincidentally, I have a MBP with the exact same symptoms you have, so the output here works perfectly!) The key here is that under 'Amperage' we get a '0' which means there is literally no current coming from the battery (Note: even though it may have voltage, if there are no amps, it won't have the 'power' to supply).
If we unplug the power adapter, the battery has nothing to supply so the computer shuts off.
The Fix
You just need a new replacement battery battery (I suggest getting ones with at minimum a 12 month warranty; 18 month is better). From personal experience, the more 'warranted' batteries lasted much longer. Definitely avoid the ones with less than a 12 month warranty no matter how inexpensive they are.
To replace the battery; it's actually very simple. Just remove the screws holding the back cover in place.
Then, just remove the screws holding in the battery and swap. Just be careful when disconnecting the battery from the logic board. Don't yank it off, use a spudger or similar tool to disconnect the molex connector by 'wedging' it off.
Reverse the procedure to reassemble. Make sure you note where each screw comes from as they are different.
That's it. Your MBA will now be able to hold a charge like it did when new.

Laptop Turns Off When Power Cord Is Removed Hp

Laptop computers are designed to operate with both AC adapters and batteries as power sources but can properly function when receiving power from only one source. Dell says a laptop does not draw from the battery power at all when connected to an outlet via an AC adapter. The laptop will work just fine if the battery has been removed from the device, but it has to remain tethered to a power source through the AC adapter at all times to function.
Power without a Battery
Aging laptop batteries can lose their ability to hold a charge to the point where the battery is no longer able to power the laptop. The laptop can still be used with a dead battery through AC adapter power only because the laptop is designed to switch between power sources: it doesn't draw power from the battery when the AC adapter is in use. Bloomberg Business weekly says manufacturers are hesitant to endorse using a laptop without the battery because it leaves the charging terminals exposed on the bottom of the computer, making the sensitive part easier to damage.

The Battery is a Backup
A laptop's battery is actually the device's secondary power source: the AC adapter is the primary. PCWorld says battery usage is intended for times when AC power is not available. The battery is used to maintain power to the laptop in the event that the AC adapter power source is either unavailable or cut from the system. Unless the battery is being charged through an external charging device, the battery relies on the AC adapter connection to the computer to charge.

Normal Power Troubleshooting Process
Removing a laptop's battery and running the device from AC power only is a commonly used step in diagnosing a power problem with a laptop computer. PC Magazine writes that you can diagnose a battery problem by removing the battery and running the laptop on AC adapter power only. The problem is usually with the battery itself if the laptop works fine without the battery connected but has problems working when the battery is installed. CBS Moneywatch says that running a laptop on AC adapter power only is a way to confirm that the AC adapter is functioning.

Without Battery Disadvantages
Running a laptop without a battery leaves the device at high-risk of power loss. If you continually run the laptop from an AC adapter, you may opt to remove the battery during use to extend the battery's life for when you need it. Wired says that keeping a laptop plugged in all the time can shorten a battery's lifespan. However, running a laptop without a battery puts the device at a disadvantage: the device will force shut down instantly if the cord is unplugged or the power goes out. Laptop charger ports are notorious for breaking from wear-and-tear: the port may get to the point where wiggling the AC adapter cable makes the difference between full power and no power.

I have no idea what is causing this truly bizarre problem. Whenever I connect or disconnect my power cable for my brand-new laptop, the screen briefly turns off (2-4 seconds). Its really annoying and I would like to know what is causing it, or how to fix it.. if it is fixable at all. I haven't seen any other reports of this problem across any forums I know, yet it seems the display model at Best Buy has the same issue mine does, so this is a right-out-of-the-box problem and not something I did when setting up. It doesn't seem like a screen malfunction (no tearing or distortion or flickering), it looks more like the way the screen turns off briefly when I disable one of my GPUs or change the screen resolution or whatever. My best guess might be that it is using the built-in Intel GPU when on battery and the GTX 1060 when plugged in, and the blackscreen is a result of switching between them, but I'm not sure how I might test that theory. I upgraded from an ASUS ROG GL551JW from 2015, which didn't have this quirk. Comments are closed.
